Condere 32V20 P50-352V5.0 mainboard firmware, USB recovery, eMMC issues, panel matching

User question

Condere 32V20 / P50-352V5.0

Artificial Intelligence Response

Direct answer to the question

• The P50-352V5.0 is a universal Smart‑TV mainboard used by several budget brands (e.g., Condere 32V20, HI, ROCH). Firmware exists, but it is panel‑specific and stored in onboard eMMC, so you must match both the board and the LCD panel model to avoid a brick. (elektroda.com)
• A USB‑upgradable package for P50‑352V5.0 (file name typically “HISI352S.bin” for 1366×768/32") is available from technician repositories; use only if your panel and hardware match. (kazmielecom.tech)

Key points

• Confirm your panel model (on the LCD label) before flashing.
• Prefer a USB recovery first; if that fails and eMMC is bad, an off‑board reflash of eMMC may be required.
• Do not mix firmware between different panels (HV320FHB‑F41, HV320WHB‑F56, PT320AT02‑2, etc.). (dumptv.ru)

Detailed problem analysis

• Symptom profile: “Stuck on Condere logo/boot loop” on 32V20 with P50‑352V5.0 is consistent with corrupted system partitions or aging eMMC. A field report for this exact set/board confirms the issue and notes an ARM “HISEMI” SoC and onboard eMMC (no socketed NAND). (elektroda.com)
• Chassis variability: The same P50‑352V5.0 board ships with multiple 32" HD panels from different vendors. Verified pairings include:
  • HV320FHB‑F41 (HI RX‑32F02FB) with USB firmware available. (dumptv.ru)
  • HV320WHB‑F56 (HI RX‑32H01FB) reported in service forums. (forum-monitor.net.ru)
  • PT320AT02‑2 (ROCH RH‑LE32DSA‑C) with a full eMMC image dump. (remont-aud.net) This diversity is why panel‑matched images are mandatory.
• Storage medium: Multiple sources list eMMC as the storage device for this chassis, which explains logo‑loop failures when the eMMC develops bad blocks. (remont-aud.net)
• Availability of firmware: Technician repositories host USB‑upgradeable packages for P50‑352V5.0 (often split archives that extract to “HISI352S.bin” for 1366×768/8 GB eMMC/32"). These are not brand‑official but are widely used in service. (kazmielecom.tech)

Current information and trends

• Recent technician threads (Oct 2025–Feb 2026) still report requests for Condere 32V20/P50‑352V5.0 USB firmware, reinforcing that official vendor channels are scarce and community repositories remain the practical path. (elektroda.com)
• Multiple cross‑brand uploads for P50‑352V5.0 (HI, ROCH) show continued use of this board with panel‑tuned builds, some provided as USB packages and others as full eMMC images. (dumptv.ru)

Supporting explanations and details

• Why panel matching matters: The firmware bundle contains LVDS timings, TCON mappings (JEIDA/VESA), gamma tables, and EDID/panel init parameters. A mismatch can cause no image, solarized colors, wrong scan direction, or repeated boot failure even if the OS portion is valid.
• Typical identifiers you need from your TV:
  • Board silkscreen: P50‑352V5.0 (already known).
  • LCD panel sticker (e.g., HV320FHB‑F41 / HV320WHB‑F56 / PT320AT02‑2).
  • Brand/model (Condere 32V20) and any software version label if visible. (dumptv.ru)

Ethical and legal aspects

• Using third‑party firmware carries IP/licensing risks and no warranty; proceed only if you own the device and accept service risk.
• Safety: Unplug mains power before opening the set. Avoid shorting keypads/pads while powered.

Practical guidelines

Implementation (USB recovery first)

1. Identify your panel model from the LCD label.
2. Obtain a P50‑352V5.0 USB package that explicitly matches your panel and resolution (32", 1366×768 is common for Condere 32V20). If using Kazmi Elecom’s 1366×768 pack, extract all parts to get the upgrade file (commonly “HISI352S.bin”). (kazmielecom.tech)
3. Prepare a small USB 2.0 stick (4–8 GB), FAT32, copy the bin to the root (no folders).
4. Force‑update methods used on this chassis:
   • Hold the TV’s side Power key, plug AC, keep holding until LED/activity shows update.
   • Or power on with the USB inserted and wait 1–2 min for auto‑detect. (Exact keying can vary by vendor build; community packages for this board are intended for USB recovery.) (dumptv.ru)
5. After a successful flash, the set reboots. If image is inverted or colors are wrong, correct in the service menu (commonly Source → 2580) by adjusting Mirror and LVDS Map/JEIDA. Save and reboot. (kazmielecom.tech)

If USB recovery fails

• Hardware check: Verify main rails on the board (5 V, 3.3 V, 1.8 V). Brownouts on 1.2–1.3 V core or 1.8 V DRAM can stall boot.
• eMMC path: Acquire a full eMMC image that matches your panel (e.g., PT320AT02‑2 for ROCH, etc.) and program the eMMC off‑board with a suitable programmer, or swap the mainboard with a known‑good P50‑352V5.0 pre‑loaded for your panel. (remont-aud.net)

Potential challenges and how to overcome them

• Board but wrong panel: If the TV boots but picture is wrong, first try Service Menu adjustments; if that fails, you likely need a build compiled for your specific panel.
• No reaction to USB: Try a different, smaller USB stick, re‑format FAT32, different USB port, and ensure correct filename per package notes. If still dead, suspect eMMC or PMIC fault.

Possible disclaimers or additional notes

• Specs posted for P50‑352V5.0 vary by vendor (Android version, CPU clocks); rely on board/panel matching rather than marketing specs. The reliable anchors are the board code and the panel model. (kazmielecom.tech)
• Not all community packages are interchangeable; several confirmed pairings exist (HV320FHB‑F41, HV320WHB‑F56, PT320AT02‑2). (dumptv.ru)

Suggestions for further research

• Post your exact panel code and a clear mainboard photo; with that, we can shortlist a known‑good USB package.
• Check active technician repositories for P50‑352V5.0 images tied to your panel family; recent requests and uploads show continuing support/activity. (elektroda.com)

Brief summary

• For Condere 32V20 with P50‑352V5.0, a panel‑matched USB firmware (“HISI352S.bin” 1366×768 for many 32" sets) is available from technician repositories; confirm your LCD panel model first, then perform a USB recovery. If the USB path fails, plan for eMMC reprogramming or mainboard swap with the correct preloaded image. (kazmielecom.tech)

Quick next step for you

• Please share the panel model printed on your LCD (photo if possible). With that, I’ll point you to the safest matching firmware package and the exact flashing steps for your unit.
